Improving Convolutional Neural Networks: The weaknesses of the MNIST based datasets and tips for improving poor datasets

Introduction In our previous tutorial series, we looked at sign language recognition using the sign language MNIST dataset based off the original 1999 MNIST dataset, which is considered the “Hello World” of machine learning. We did this because we wanted a practical example that could be trained on a standard CPU. The sign language MNIST […]

Vitis AI using Tensorflow and Keras Tutorial Part 8

Part 8: Compiling our CNN We now have our complete model and must make it ready to be run on the FPGA. To do this, we must compile our model with the Vitis AI compiler which will convert and optimise our model into a format that is runnable on the DPU. This tutorial will focus […]

Vitis AI using Tensorflow and Keras Tutorial Part 7

Part 7: Quantising our graph In our previous tutorial we produced our frozen model so now we can optimise it to make it run on our FPGA hardware efficiently, which we can do through quantisation. Quantisation is the process of reducing the number of bits used for our tensors and weights, but exactly why is […]

Vitis AI using Tensorflow and Keras Tutorial part 6

Part 6: Converting and Freezing our CNN Now we have built a more optimal CNN by handling both under-fitting and over-fitting, we can begin the process of deploying our model on the FPGA itself. The first step in this process is to convert our Keras model to a TensorFlow model and then we need to […]

Vitis AI using Tensorflow and Keras Tutorial Part 5

Part 5: Optimising our CNN In our previous section, we both trained our network on a training set and tested it on a testing set and our accuracy on the training set (0.972) was higher than on our testing set (0.922). In an ideal design the training set should have the same accuracy as the […]
